Porky Pigs

A pair of wild pigs copulate among their herd mates in a protected area in Tennessee.

Sows typically have five to six piglets per litter and can give birth twice per year, giving them one of the fastest reproduction rates of any large mammal. Frequent mating has helped this invasive species spread quickly, and they often become a pest species. They aggressively root through the leaf litter consuming seeds and seedlings, thus crippling the next generation of forest regeneration.

Surprise!

A cougar is surprised to find a camera trap on a tree at 11 a.m. in Manaus, Brazil. Although more active at night, cougars are not strictly nocturnal and can be found active at any time of the day or night.

Mirror, Mirror

Camera trapper Xavier Hubert-Brierre put this large mirror on the side of a road through the jungle in Gabon and left a camera there to record how the animals would respond to their own reflections.

A different silverback gorilla saw its own reflection and responded with aggression, trying to scare off a potential challenger. However, his younger son, pictured to the left, sees a playmate in his own reflection and walks up to kiss the mirror.

Peek-a-Boo

This mother wombat appears to be sitting on its joey, but the youngster is actually peering out from the comfort of its pouch, which faces backward to avoid collecting dirt when the mother digs a new burrow.

Perplexed Pair

Long-tailed macaques are a common species in Southeast Asia and live a bold and curious lifestyle. Although about half of their diet is fruit, they are always on the lookout for a small insect or lizard to pounce on. They also beg for handouts from tourists, congregating in huge groups at temple sites.

Little Bandit

Across their range, northern raccoons are typically one of the most common mammals, especially in areas that have water or human development nearby, supplying streams or rubbish for them to forage through. This animal from the Florida Keys has plenty of people and water around to live a prosperous raccoon lifestyle.

Hitching a Ride

The genet might be using this rhino as a movable hunting blind, waiting for mice or insects to run out of the way of the big lumbering beast and then pouncing on them from above. Genets are great jumpers and climbers and presumably would have little problem getting onto the back of a slow-moving rhinoceros.
